Go to Project settings >Project team
Click the "three-dot menu" to the right of the person's name.
Choose the Remove from project option. This removes the person from your current project. They may still be authorized in other projects.
Removing a collaborator only removes the user from the current active project. Not all of your projects. If you want to remove a user from multiple projects, repeat this process in all the projects they are assigned to.
If you want to delete a user system-wide and are not sure which projects they are assigned, send an email to [email protected], and we can delete the user from the entire system. This process can not be undone.
